The Role

The Ecclesfield facility is fully dedicated to the manufacture of acoustic enclosures used across critical, high-integrity industries. With demand increasing, we’re looking for a confident, organised and quality-driven Supervisor who can take ownership of night-shift output, support and guide a skilled fabrication workforce, and maintain the standards Hartwell is known for.

This is a hands-on leadership position: you’ll balance oversight with practical involvement, ensuring work flows smoothly, safely and to the required level of precision.

• Liaise with management where required on progress, issues, resource needs and improvements

• Uphold Hartwell’s values of cooperation, integrity and taking pride in the work

What You’ll Bring

• Strong background in fabrication and/or welding, ideally within structural steel or enclosure manufacturing

• Previous supervisory, team-lead or charge hand experience

• Ability to read and interpret technical drawings with confidence

• Calm, organised approach with good decision-making skills

• A leadership style that supports people, builds capability and ensures accountability

• Commitment to quality, safety and consistent workmanship

What the Role Offers

• Night shift, Monday to Thursday: 12-hour shifts

• Overtime opportunities on Fridays

• A stable, permanent leadership position in a growing business

• The chance to shape and develop a newly formed night-shift team

• A supportive, family-owned environment where skilled work is genuinely valued
